Geri Horner is pregnant

Geri Horner is pregnant.

The former Spice Girls singer - who already has 10-year-old daughter Bluebell from a past relationship - and her husband Christian Horner, 42, are "overjoyed" to be expecting their first child together.

A spokesperson for the 44-year-old star confirmed: "Geri and Christian are absolutely delighted to announce they are expecting their first child together.

"The couple are overjoyed with the good news and cannot wait to welcome the newest addition to their family."

Geri borrowed a line from her single 'It's Raining Men' to announce her happy news on Instagram.

She wrote: "God bless Mother Nature #mamaspice (sic)"

She also shared as sketch of a heavily pregnant woman alongside the caption.

Geri previously described Formula One boss Christian - who she married last year - as her "best friend".

She said: "My husband is my best friend. He knows me inside out, I don't edit myself with him. It was a big learning curve."

And late last year, the 'Lift Me Up' hitmaker admitted she and Christian - who has a three-year-old daughter, Olivia, from a past relationship - would love to have another child and would even consider adoption.

She said: "If it happens it happens and that will be amazing. But we are already blessed with two girls.

"We might think about adoption but to be honest, we know we are so lucky and so happy with things as they are, you have to realise when not to push your luck."
